“We couldn't be more delighted to be bringing this amazing community event to our area,” said Lyndsi Lane, vice president of GateHouse Live. “We expect that with the widespread popularity of Disney's Peyton List, coupled with the sheer volume of activities for toddlers to teens, we will draw a crowd from across eastern Massachusetts.”
